[Silent microhemorrhages in patients with symptomatic cerebrovascular disease].

Introduction: T2*-weighted gradient echo MRI sequences (T2*-MRI) have made it possible to detect cerebral microhemorrhages (MH) that have been considered as subclinical but whose clinical significance is largely unknown.

Objective: To establish the frequency of MH in a sample of consecutive symptomatic cerebrovascular disease (SCD) patients, analyzing its associations with different vascular risk factors (VRF) and its clinical significance.

Methods: A total of 198 patients with SCD were consecutively examined using T2*-MRI.

Placebo response in a patient with chronic migraine and ergotic overuse.

Facilitation of nociceptive systems has been implicated in Chronic-Migraine pathogenesis. Daily consumption of medication may be a contributing factor. The patient was male, aged 76 years, with history of migraine without aura.
